Netgear Arlo Go A-2 Replacement Battery 7.2V 3000mAh

Netgear Arlo Go (VML4030 / VMA4410) — 7.2V Li-ion Replacement Battery (A-2)

This is a 7.2V 3000mAh Li-ion replacement battery for the Netgear Arlo Go cellular security camera. It fits the VML4030 and VMA4410 models and matches the OEM A-2 specification. At 21.6Wh, it restores full operating capacity to cameras where the original cell has degraded through repeated charge cycles.

• VML4030 and VMA4410 compatibility: Both models run on the same 7.2V battery rail and use the same connector and BMS handshake. The A-2 cell is the single battery spec across the Arlo Go line, so one part number covers both variants.
• Bench tested on actual hardware: We cycled this battery through full charge and discharge on the Arlo Go platform. The BMS responded correctly to charge termination, low-voltage cutoff, and thermal monitoring at ambient temperature.
• First-install power cycle: After fitting this battery, power cycle the camera once through the Arlo app. The firmware must register the new cell before motion recording events log correctly to cloud storage — skipping this step can cause missed clips even when the camera appears online.

Motion trigger dropout on the Arlo Go after a battery swap

When motion triggers on the Arlo Go, the IR LEDs and image processor fire simultaneously, creating a combined current spike that can exceed the BMS protection threshold on a partially discharged cell. If the resting voltage is below approximately 7.0V, the BMS may momentarily cut output rather than sustain the spike, resulting in a missed detection event with no clip saved. This is not a camera fault — it is the BMS protecting the cell under high instantaneous load. Keep the battery charged above 50% in high-traffic areas where frequent motion events cluster closely together.

App showing 0% or incorrect battery percentage after install

The Arlo Go does not use a fuel gauge IC — it reads battery percentage by mapping resting voltage against a fixed threshold table in firmware. A freshly installed cell that has not completed one full charge-to-discharge cycle will sit at a voltage point the firmware has not yet calibrated against, which causes the app to display 0% or a stale percentage from the previous battery. Run one complete charge cycle through the Arlo app after installation. After the cycle completes, the displayed percentage will align with actual cell state.
